NOTES AND CORRESPONDENCE. 
A Fifty Pound Prize for Observations with the Microscope.— 
We beg to call the attention of our readers to the following 
advertisement : 
“MICROSCOPIC INVESTIGATION. 
“‘ Firry Sovererens will be given for the best Report on the Results of 
Microscopic Observation, applied to the Vegetable Physiology of Agricul- 
ture. 
“Tt is not thought desirable to confine the observer too strictly to any 
particular line of researches, the only necessary limit being, that the plants 
to be examined and reported upon shall be selected from those commonly 
cultivated ; such as the cereals, or those usually known under the names of 
pulse, root, or fodder crops. The structural formation of these plants—their 
ordinary vital processes—modifications of the above induced by climatic 
influences or the application of manure—morbid changes of their tissues 
consequent upon the attacks of insects or disease,— would all prove extensive 
and interesting fields of inquiry; and it must be left to the writers them- 
selves to select those particular branches of the subject on which they are 
able to supply the greatest amount of original iuvestigation.” 
This prize is offered by the Royal Agricultural Society of 
England, and the report is to be sent in during the month of 
March, 1858. The subject is a very interesting one, and 
some of our young vegetable physiologists could not enter 
upon a more interesting field of investigation.
